Nursing Elites

1. The nurse is preparing to give a dose of a cephalosporin medication to a patient who has been receiving the antibiotic for 2 weeks. The nurse notes ulcers on the patient’s tongue and buccal mucosa. Which action will the nurse take?

• A. Hold the drug and notify the provider.
• B. Obtain an order to culture the oral lesions.
• C. Gather emergency equipment to prepare for anaphylaxis.
• D. Report a possible superinfection side effect of the cephalosporin.

Correct answer: D

Rationale: The nurse should report a possible superinfection side effect of the cephalosporin to the physician as the patient's symptoms may indicate a superinfection that requires treatment. Holding the drug is not necessary unless directed by the provider. Culturing the lesions is not indicated for this situation. There is no evidence to suggest impending anaphylaxis based on the patient's symptoms.

2. Which is a characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections?

• A. Sulfonamides are bactericidal.
• B. Sulfonamides are synthetic compounds.
• C. Sulfonamides have antifungal and antiviral properties.
• D. Sulfonamides increase bacterial synthesis of folic acid.

Correct answer: B

Rationale: The characteristic that distinguishes sulfonamides from other drugs used to treat bacterial infections is that sulfonamides are synthetic compounds, not derived from biologic substances. Choice A is incorrect because sulfonamides are bacteriostatic, not bactericidal. Choice C is incorrect because sulfonamides do not have antifungal and antiviral properties. Choice D is incorrect because sulfonamides act by inhibiting bacterial synthesis of folic acid, not increasing it.

3. When a patient is receiving high doses of a cephalosporin, which laboratory values will this patient's nurse monitor closely?

• A. Blood urea nitrogen (BUN), serum creatinine, and liver function tests
• B. Complete blood count and electrolytes
• C. Serum calcium and magnesium
• D. Serum glucose and lipids

Correct answer: A

Rationale: When a patient is receiving high doses of a cephalosporin, such as cefazolin, the nurse should closely monitor laboratory values that indicate renal and hepatic function. This includes checking the Blood Urea Nitrogen (BUN) and serum creatinine levels to assess kidney function. Additionally, monitoring liver function tests, such as AST, ALT, ALP, LDH, and bilirubin, is essential as cephalosporins can affect liver enzymes. Therefore, options B, C, and D are incorrect as they do not specifically address the parameters that are most pertinent when administering high doses of cephalosporins.

4. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?

• A. Complete blood count (CBC)
• B. Electrocardiogram (ECG)
• C. Chest X-ray
• D. Serum electrolytes

Correct answer: B

Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.

5. In a patient with chronic kidney disease, which of the following is a common complication?

• A. Hyperkalemia.
• B. Hypernatremia.
• C. Hypocalcemia.
• D. Hyperphosphatemia.

Correct answer: A

Rationale: Hyperkalemia is a common complication in chronic kidney disease due to the kidneys' reduced ability to excrete potassium. As kidney function declines, potassium levels may increase, leading to hyperkalemia. Hypernatremia (increased sodium levels), hypocalcemia (low calcium levels), and hyperphosphatemia (elevated phosphate levels) are not typically associated with chronic kidney disease. Therefore, the correct answer is hyperkalemia.
